We are moving Microsoft To Do’s backend to a more efficient service. For the best experience across all of your devices, you need to update to the latest version. Make sure your mobile and desktop To Do apps are version 2.49 or higher before end of October 2021 to avoid any issues with cross device syncing. Also since To Do tasks are also linked with Outlook Android and iOS apps. Please make sure that you update your Outlook android and iOS apps as well. If your organization does not use Microsoft To Do, you can disregard this message.
